How does the temperature of a magnet affect its characteristics?

WebFor my science fair project, I chose to test out if temperature can have an affect on magnetism. I hypothesized that the lower the temperature is of the magnet, the stronger it would be. I guessed this based this estimate from my background knowledge on the topic. From what I know, a magnet’s source of attraction comes from the magnetic fields. WebJun 10, 2014 · When heated above 176° Fahrenheit (80° Celsius), magnets will quickly lose their magnetic properties. The magnet will become permanently demagnetized if exposed to these temperatures for a certain length of time or heated at a significantly higher temperature ( Curie temperature ).
